I noticed a little gray fleck of plastic on the floor of my RV-9A. Investigated and discovered the backshell of one of the d-sub connectors on my EIS 4000 was crumbling at the screw locations. Not a great photo but it gives you the gist:
This is presumably the d-sub connector that was installed by the builder back in the 2005-2007 time frame.
And there's more: the crumbling pieces (one chunk fell off into my fingers when I touched the connector) felt slightly oily, as if they had just the tiniest misting of a really light machine oil.
I didn't see any obvious signs of staining, leaks, etc. anywhere behind the panel, but I didn't do any really serious spelunking yet.
What's going on here, do you think?
Also: what brand/kind of backshell should I replace it with? Given the joys of rooting around behind the panel, I'd like something as durable as possible!
Thanks in advance for any ideas.
